From the article:
Ms. Ford’s “Bang,” which featured the creator, Lee Etzold and Sarah Sanford portraying loopy female archetypes — the nerd, the bourgeois, the hippie — was one of the breakout hits of the festival, which concludes on Sunday. The production added several performances, and the audience I saw it with at a late show on a Friday night delighted in its spirited humor and the, ahem, cheeky audacity with which its performers frolicked frockless in and around the audience, seducing more than one member to join in the sexually tinged antics.
